In case that you control LED via port pin and npn-transistor
Change the design. Most '51 derivatives are so poor re Ioh that using a high port pin for anything else than driving a CMOS circuit is gambling at best. With some derivatives, however, it is not a problem. Which derivative (ALL letters and numbers, please) are you using? Erik |

Your LED driver is a misconstruction! | 01/01/70 00:00 |
